From DX Heat


This past month saw the Magic Band, 6 meters, come alive on schedule with the annual Sporadic E activity at unprecedented levels due to the popularity of FT8.  A number of club members made dozens of 6m QSOs with stations across the USA, Canada, and Mexico and a few of us were lucky enough to catch multi-hop openings to Europe and Asia.  The most memorable activity occurred on the morning of June 7th when I logged CT1IUA, EA5BY, EA5ISZ, PA2M, CT1BXT, EA6VQ, ON4GG, and EA1YV between 1529Z and 1700Z.  Other club members logged many more European stations during this time and nearly all of it was done on the FT8 digital mode.

We are eagerly awaiting the upcoming DXpedition to Baker Island in the Pacific by the Dateline DX Association using the callsign KH1/KH7Z.  Two CADXA members will be on that team – Ned Stearns, AA7A, and Bud Semon, N7CW.  We wish them a safe and smooth journey and hope to hear them on many bands and modes.  This will be the first opportunity to see whether the new DXpedition version of FT8 (Fox/Hound) that Ned helped develop can run at rates greater than ever seen before on a digital mode.  You need to be prepared by downloading WSJT-X version 1.9.1 or later and selecting “Hound” on the File/Settings page, Advanced tab.  Don't forget to uncheck it when you go back to normal FT8 contacts.

For those of you beginning the FT8 transition, I have added a wonderful guide full of tips to this website on how to set up your station and operate this evolving mode.  Click on the "DX Resources" tab and look down the page for "FT8 Tips for DXers" by G3IFB/ZL3IFB.  It is good reading for experienced FT8 users as well with several tips that you may not have considered.

We were recently informed that the ARRL Foundation awarded the 2018 CADXA $1,000 College Scholarship to Lukas J. Severinghaus, KK6AXQ, of Flagstaff, Arizona.  We want to extend our congratulations to Lukas and wish him success in his academic endeavors this next semester.

We had over 40 members and guests in attendance at the June Meeting.  Our speaker was Dave Jorgensen, WD5COV, from Deming, New Mexico.  Dave gave a terrific talk on the March 2018 9M0W DXpedition to the Spratley Islands by a large international team. 

This was a lesson in how Murphy can strike even the best planned DXpeditions.  Although the team made 23,460 contacts, they had hoped to do twice as many, but were unexpectedly delayed two days in arriving on the island and then had power issues at the resort where they set up their stations.

It was fascinating to hear how this island was expanded dramatically in size using landfill so that an airstrip could be built to accommodate visitors from around the globe who come to scuba dive in the nearby coral reefs.

Welcome to the Central Arizona DX Association



The July Meeting will be at 7:00 pm on Thursday night, July 5th, at the PERA Club. 

Our program will be “The Andaman Island DXpedition to VU4G” presented via Skype by CADXA Honorary Member John Warburton, G4IRN.  John has graciously agreed to interrupt his sleep in England to make this presentation.  This was a remarkable DXpedition on many levels, but most significantly because of the fact that John ended up operating alone after the other three members of his team dropped out for various reasons.  Come and hear his interesting story and the gamble he took that a license would be issued upon his arrival after a lengthy journey from England to India. 

Please feel free to arrive early to socialize with your friends.  Refreshments will be served at the break.  Guests are always welcome. .
